INFORMED CONSENT FOR ZOOM!® TOOTH WHITENING TREATMENT INTRODUCTION
This information has been given to me so that I can make an informed decision about having my teeth
whitened. I may take as much time as I wish to make my decision about signing this informed consent
form. I have the right to ask questions about any procedure before agreeing to undergo the procedure.
My dentist has informed me that my teeth are discolored and could be treated by in-office whitening
(also known as “bleaching”) of my teeth.
DESCRIPTION OF THE PROCEDURE
Zoom! in-office tooth whitening is a procedure designed to lighten the color of my teeth using a
combination of a hydrogen peroxide gel and a specially designed ultraviolet lamp. The Zoom!
treatment involves using the gel and lamp in conjunction with each other to produce maximum
whitening results in the shortest possible time. During the procedure, the whitening gel will be applied
to my teeth and my teeth will be exposed to the light from the Zoom! lamp for three (3), 15-minute
sessions. During the entire treatment, a plastic retractor will be placed in my mouth to help keep it
open and the soft tissues of my mouth (i.e., my lips, gums, cheeks and tongue) will be covered to
ensure they are not exposed to either the gel or light. Lip balm (SPF rating: 30+) may also be applied
as needed and I will be provided an ultraviolet light filter for my eyes. After the treatment is
completed, the retractor and all gel and tissue coverings will be removed from my mouth. Before and
after the treatment, the shade of my upper-front teeth will be assessed and recorded.
I understand I may decide not to have the Zoom! treatment at all. However, should I decide to undergo
the treatment, I understand there are alternative treatments for whitening my teeth for which my dentist
can provide me additional information. These treatments include:
Whitening Toothpastes/Gels Other In-office Whitening Treatments
Take-Home Whitening Kits
I understand that the cost of my Zoom! treatment is determined by my dentist. I understand that my
dentist will inform me if there are any other costs associated with my Zoom! treatment.
RISKS OF CONSENT FOR TREATMENT
I also understand that Zoom! treatment results may vary or regress due to a variety of circumstances. I
understand that almost all natural teeth can benefit from Zoom! whitening treatments and significant
whitening can be achieved in most cases. I understand that Zoom! whitening treatments are not
intended to lighten artificial teeth, caps, crowns, veneers or porcelain, composite or other restorative

materials and that people with darkly stained yellow or yellow-brown teeth frequently achieve better
results than people with gray or bluish-gray teeth. I understand that teeth with multiple colorations,
bands, splotches or spots due to tetracycline use or fluorosis do not whiten as well, may need multiple
treatments or and may not whiten at all. I understand that teeth with many fillings, cavities may not
lighten and are usually best treated with other non-bleaching alternatives. I understand that
provisionals or temporaries made from acrylics may become discolored after exposure to Zoom!
I understand that Zoom! treatment is not recommended for pregnant or lactating women, light sensitive
individuals, patients receiving PUVA (Psoralen + UVA radiation) or other photochemotherapeutic
drugs or treatment, as well as patients with melanoma, diabetes or heart conditions. I understand that
the Zoom! Lamp emits ultraviolet radiation (UVA) and that patients taking any drugs that increase
photosensitivity should consult with their physician before undergoing Zoom! treatment.
I understand that the results of my Zoom! Treatment cannot be guaranteed.
I understand that in-office whitening treatments are considered generally safe by most dental
professionals. I understand that although my dentist has been trained in the proper use of the Zoom!
whitening system, the treatment is not without risk. I understand that some of the potential
complications of this treatment include, but are not limited to:
Tooth Sensitivity/Pain – During the first 24 hours after Zoom! treatment, some patients can
experience some tooth sensitivity or pain. This is normal and is usually mild, but it can be worse in
susceptible individuals. Normally, tooth sensitivity or pain following a Zoom! treatment subsides
within 24 hours, but in rare cases can persist for longer periods of time in susceptible individuals.
People with existing sensitivity, recession, exposed dentin, exposed root surfaces, recently cracked
teeth, abfractions (micro-cracks), open cavities, leaking fillings, or other dental conditions that cause
sensitivity or allow penetration of the gel into the tooth may find that those conditions increase or
prolong tooth sensitivity or pain after Zoom! treatment.
Gum/Lip/Cheek Inflammation – Whitening may cause inflammation of your gums, lips or cheek
margins. This is due to inadvertent exposure of a small area of those tissues to the whitening gel or the
ultraviolet light. The inflammation is usually temporary which will subside in a few days but may
persist longer and may result in significant pain or discomfort, depending on the degree to which the
soft tissues were exposed to the gel or ultraviolet light.
Dry/Chapped Lips – The Zoom! treatment involves three, 15-minute sessions during which the mouth
is kept open continuously for the entire treatment by a plastic retractor. This could result in dryness or
chapping of the lips or cheek margins, which can be treated by application of lip balm, petroleum jelly
or Vitamin E cream.

Cavities or Leaking Fillings – Most dental whitening is indicated for the outside of the teeth, except
for patients who have already undergone a root canal procedure. If any open cavities or fillings that
are leaking and allowing gel to penetrate the tooth are present, significant pain could result. I
understand that if my teeth have these conditions, I should have my cavities filled or my fillings redone
before undergoing the Zoom! treatment.
Cervical Abrasion/Erosion – These are conditions which affect the roots of the teeth when the gums
recede and they are characterized by grooves, notches and/or depressions, that appear darker than the
rest of the teeth, where the teeth meet the gums. These areas appear darker because they lack the
enamel that covers the rest of the teeth. Even if these areas are not currently sensitive, they can allow
the whitening gel to penetrate the teeth, causing sensitivity. I understand that if cervical
abrasion/erosion exists on my teeth, these areas will be covered with dental dam prior to my Zoom!
Root Resorption – This is a condition where the root of the tooth starts to dissolve either from the
inside or outside. Although the cause of this is still uncertain, I understand that there is evidence that
indicates the incidence of root resorption is higher in patients who have undergone root canals
followed by whitening procedures.
Relapse – After the Zoom! treatment, it is natural for the teeth that underwent the Zoom! treatment to
regress somewhat in their shading after treatment. This is natural and should be very gradual, but it can
be accelerated by exposing the teeth to various staining agents. Treatment usually involves wearing a
take-home tray or repeating the Zoom! treatment. I understand that the results of the Zoom! treatment
are not intended to be permanent and secondary, repeat or take-home treatments may be needed for me
to maintain the tooth shade I desire for my teeth.
The safety, efficacy, potential complications and risks of Zoom! treatment can be explained to me by
my dentist and I understand that more information on this will be provided to me upon my request.
Since it is impossible to state every complication that may occur as a result of Zoom! treatment, the list
of complications in this form is incomplete.
The basic procedures of Zoom! treatment and the advantages and disadvantages, risks and known
possible complications of alternative treatments have been explained to me by my dentist and my
dentist has answered all my questions to my satisfaction.
In signing this informed consent I am stating I have read this informed consent (or it has been read to
me) and I fully understand it and the possible risks, complications and benefits that can result from the
Zoom! treatment and that I agree to undergo the treatment as described by my dentist.
